Application filed April 13, 1917. Sien-'tel No. M1349.

To all 'whom'z't may concern:

Beit known that I, JAMES H. Sauna, a citizen of the United States, and resident of Rochester, in` the county of Monroe and Stateof New York, have invented'certain new and useful improvements in Auto' mobile-Bumpers, of which the following is a specification.

To these and other ends, the invention consists of certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claim.-

ln the drawings :-u Figure 1 is a .view3 partly Vin section, 'showing' the bumper supporting-arm attached to' the curved forward end oi a :trame bar of a motor vehicle;

Fig. 2 is a plan view of the supportingL arm and the forward end of the frame bar; and

Fig. 3 is a section on the line 3-3, Fig. l. Referring more particularly' to the drawforward end ot' the frame bar ofv channel form, and 2 the bumper bar which extends transversely of the vehicle and is supported, near opposite ends, by two supporting arms. These supportin arms are, 'in this instance, each forme of an outer member 3 secured to the bumper bar and guided in an inner member 4, la spring 5 being interposed between the two members to vhold them normally` extended, but to permit the bumper bar to yield upon impact with any object.

The inner member 4 has, in this instance,

a, rearward extension 6 formed with a verti-A cal face to engage the vertical face of the frame bar i. rlhis vertical face of the en. tension 6 is preferably channeled or curvedE in order that it may .tit over any rivets or small projectionson the side .face 'of the frame bar. The, extreme end of the entens sion 6 is deflected upwardly at 7, and ie provided with a slot 8 which lies atan acute angle to the length of the bumper supporting arm. To one side of the slot 8 the extension 6 is provided with a bolt opening,

and from the inner side oi the extension a grooved or channeled projection 9 extends to lie under the frame bar i. Extending through the opening in the `extension 6, and also through the channel of the extension 9, is a hooked bolt l0, the hook of vwhich en gages the lower flange' ll of the channeled frame bar l, the bolt being provided with a nut 12 cooperating with the face oi the ex tension 6. A hooked bolt l'also engages the lower iiange 1l of the channel bar l and operates in the slot 8, 'being held therein by a nut-ele..

By this invention the supporting arms of a bumper may be connected to the side orl framebars oij an automobile without utilizing thelbolts the forward ends of the frame bars, and without perforating the frame bars. two hooked bolts which are adjustable relatively to each diii'erent curvatures may be engagedrwhile maintaining the supporting arm in a horizontal position. rlhese two hooked bolts engage with'a iian'e of the channel bar, and do not interfere with the mud guard or the the automobile when they splash guard of splash or the `mud guard is securedy to the other ange. The bolts draw the supprting arm rmly against the vertical face of the side bar, and any twisting action due to the shape ofthe bar and the arrangement oi@ the bolts is prevented by the channel ertension 9 wh1ch engages the side of thefon ward bolt as a brace. In attaching the bumper, the forward bolt will act as a pivot ,while the rear bolt is adjustedin the slot to properly position the bumper on the vehicle frame bar.

Each supporting arm employs f other so that frame'bars or What I claim as my invention and desire ing the .bolt opening as a center, the arm to secure by'Letters Patent is also having an integral channeled projec- 10 A bumper supporting arm having a'vertition extending from its'channeled Jface adcal channeled face for abutting .the vertical jacent the bolt opening,v a hooked bolt fitted 5 Side face of a channeled bar with a curved in said opening and channeled projection,
